Stability in women's experiences of hassles and uplifts: a five-year follow-up survey

Hassles and uplifts, a concept used in measuring daily stress events, was applied to working mothers' everyday life. The aim was to explore the stability in working mothers' experiences in patterns of daily occupations, operationalized as hassles and uplifts, between the year 2000 (baseline) and the year 2005 (follow-up). Further, the intention was to reveal possible differences in the number, ori

Land-use effects on the functional distinctness of arthropod communities

Land-use change is a major driver of the global loss of biodiversity, but it is unclear to what extent this also results in a loss of ecological traits. Therefore, a better understanding of how land-use change affects ecological traits is crucial for efforts to sustain functional diversity. To this end we tested whether higher species richness or taxonomic distinctness generally leads to increased

Frequent CXCR4 tropism of HIV-1 subtype A and CRF02_AG during late-stage disease - indication of an evolving epidemic in West Africa

Background: HIV-1 is one of the fastest evolving pathogens, and is distinguished by geographic and genetic variants that have been classified into different subtypes and circulating recombinant forms (CRFs). Early in infection the primary coreceptor is CCR5, but during disease course CXCR4-using HIV-1 populations may emerge. This has been correlated with accelerated disease progression in HIV-1 su

Awareness of Language use in Conceptualization: A Study of Children's Understanding of Movement and Gravity

In this article the role of children's awareness of the function of language use is examined in an empirical, qualitative investigation. Forty children of six and 10 years old were asked to make sense of a science problem in special dialogue setting where they were encouraged to reflect on their own language use. The article concerns the interplay between language use and meaning-making. Dialogue

Evaluation of an immunoaffinity extraction column for enrichment of adducts between human serum albumin and hexahydrophthalic anhydride in plasma.

An immunoaffinity extraction (IAE) column was prepared for extraction of adducts between human serum albumin (HSA) and hexahydrophthalic anhydride (HHPA). HHPA is a strong sensitizer inducing immunoglobulin E antibodies in vivo. Polyclonal antibodies from a rabbit immunized with keyhole limpet hemocyananin-HHPA conjugate were purified using a Protein A Sepharose gel. To obtain antibodies with opti

Computationally efficient modelling of short fatigue crack growth using dislocation formulations

Abstract in UndeterminedIn an attempt to develop it computationally efficient model for simulation of fatigue crack growth of microstructurally short cracks two dislocation based models have been compared. In both models, the geometry of the boundary and the crack is described using dislocation dipole elements, whereas the plasticity is described either by discrete dislocations or by distributed d

Signal Modeling and Data Reduction for Wireless Brain-Machine Interfaces

Brain-machine interfaces (BMIs) provide a uni- or bidirectional communication link between the central nervous system and the outside world. This link facilitates the studying of neuronal mechanisms underlying behavior as well as the treatment of neurological disease. Wired BMIs are limited in the sense that they restrict the mobility of the subject and they increase the risks for post-surgical co

New microsatellite markers for examining genetic variation in peripheral and core populations of the Coastal Giant Salamander (Dicamptodon tenebrosus)

The Coastal Giant Salamander (Dicamptodon tenebrosus) is classified as threatened at the northern periphery of its range in British Columbia (BC), Canada, primarily due to forestry practices and habitat fragmentation. Characterising dispersal behaviour and population connectivity is therefore a priority for this region, while genetic differentiation in core versus peripheral locations remains unst

Common breast cancer susceptibility alleles and the risk of breast cancer for BRCA1 and BRCA2 mutation carriers : implications for risk prediction

The known breast cancer susceptibility polymorphisms in FGFR2, TNRC9/TOX3, MAP3K1, LSP1, and 2q35 confer increased risks of breast cancer for BRCA1 or BRCA2 mutation carriers. We evaluated the associations of 3 additional single nucleotide polymorphisms (SNPs), rs4973768 in SLC4A7/NEK10, rs6504950 in STXBP4/COX11, and rs10941679 at 5p12, and reanalyzed the previous associations using additional ca

A study of the recovery of the dietary fibres from olive mill wastewater and the gelling ability of the soluble fibre fraction

A novel method of the recovery of a dietary fibre containing material from olive mill wastewater (OMW) was developed. Extraction was based on thermal treatment with mixtures of ethanol and acids, prior to the isolation of the alcohol insoluble residue (AIR). Different mixtures were tested and the extracted residues were characterized. The maximum AIR recovery accounted 64.8 g/100 g OMW dry matter,

The development of methods for detection and assessment of safety critical events in car driving

Improving our knowledge of drivers’ behaviour, especially in hazardous situations is a key to understanding why accidents occur and how to improve safety on our roads. Crash surrogate measures have proven to be very useful in traffic safety analysis. As a valid crash surrogate measure shares the same logical chain of events as actual crashes, studying those events increases the opportunities to an

Hip Fractures - Functional assessments and factors influencing in-hospital outcome of patients with hip fracture, a physiotherapeutic perspective

A hip fracture is probably one of the most fatal fractures for the elderly and estimated worldwide to reach 5 million cases annually by the year 2050. Thus, continuing efforts in preventing fractures, with more research and improved treatment strategies for those who do fracture, seem crucial. The primary aims of this thesis, which comprises seven original papers, including a total of 656 patients

Determination of carotenoids in microalgae using supercritical fluid extraction and chromatography.

A method was developed based on supercritical fluid chromatography for quantitative determination of carotenoids in extracts of Scenedesmus sp. By utilizing the low backpressure in supercritical fluid chromatography, a C18 column and a 2-ethyl pyridine column were coupled in series. It was concluded that even minor changes in temperature had a substantial effect on selectivity. A standard mixture
